n8n-mcp and mcp-n8n-builder
These are **competitors** offering overlapping functionality—both are MCP servers that enable AI assistants to programmatically create and manage n8n workflows, with the first being significantly more mature and widely adopted.
About n8n-mcp
czlonkowski/n8n-mcp
A MCP for Claude Desktop / Claude Code / Windsurf / Cursor to build n8n workflows for you
Provides structured access to 1,396 n8n nodes with 99% property coverage and 87% documentation coverage, enabling AI assistants to generate workflow configurations from real-world templates. Operates via stdio transport with optional n8n API integration for workflow creation and execution, while maintaining safety guardrails against production modifications. Includes a pre-built database of node schemas, 2,646 extracted template configurations, and 265 AI-capable tool variants for comprehensive automation context.
About mcp-n8n-builder
spences10/mcp-n8n-builder
🪄 MCP server for programmatic creation and management of n8n workflows. Enables AI assistants to build, modify, and manage workflows without direct user intervention through a comprehensive set of tools and resources for interacting with n8n's REST API.
Implements the Model Context Protocol (MCP) standard with Zod-based schema validation and node-type verification against n8n's available nodes to prevent workflow errors before creation. Provides configurable output verbosity modes and caching to optimize token consumption, critical given that n8n workflows are complex nested JSON structures that can easily exceed LLM context windows. Exposes MCP tools and resources for full CRUD operations, execution tracking, and workflow activation/deactivation across n8n instances via REST API.
